Input & output transformers

I am looking to alter the TX1 & RX1_L for a lower frequency response.
Problem is that the schematic does not match the part numbers at all.
TX1, RX1_L, RX1-W all use the TC1-1-13MA+.
TX2 & RX1_H use TCMI-63AX+
Neither looks to be right part by the schematic, although may be the correct part number.
I just want to be sure of the units, so as to swap them out.

Thank you,

Also, found the TX impedance at the output pin of the LMS7 to be 40 ohms. I could not find the RX input impedance. Could that be supplied?

Thank you,
